Updating drivers of windows 7 and tuning
If your computer can’t handle all the work it is tasked with at the selected buffer size, you will experience pops and clicks or other artifacts in your audio output.
Please note that each of these tips may contribute to improving the overall performance of your system.Therefore, test at least both settings 256 and 512.Please consult the documentation of your audio interface to learn about its driver's latency settings.If you use a Native Instruments audio interface, you will find the latest drivers here.In your audio application, make sure you always use of the ASIO driver for your soundcard, and not the Direct Sound or WASAPI driver.This guide covers important information on how to detect and resolve audio performance issues (crackling, drop outs, artifacts) on Windows systems during audio playback.

This can be distracting when performing or recording.
The downside of using a smaller buffer size is that the smaller the buffer size / latency, the bigger the processing load on your computer.
Start out with an ASIO latency setting (buffer size) of 512 and verify if this gives you artifact-free results.
If not, increase the buffer size by one increment at a time and try again.
